ARP Chevy LS 3/8in Flange Hex Header Bolt Kit

Do it right the first time with these Bolts! Best around in fit, finish, quality! Spend the money on the right part for your application!

Great product

Did the job!

Description misleading, my headers require 3/8 -16 thread, description describes 3/8 flange not thread size

Bolts threaded in nicely. 10/10

Got these for my 2007 Silverado when replacing the engine. Considering how often the factory bolts break, my mechanic thought this was a great idea.

Installed headers. Been riding on them for about a month now.

Great price and product thanks

seem to be quality.

It fit my 05 Silverado 1500, great replacement for the oem broken exhaust manifold bolts
